Description of Related Art

In recent years, with the popularity of electronic devices having camerafunctionalities, the demand of miniaturized optical systems has beenincreasing. The sensor of a conventional optical system is typically aCCD (Charge-Coupled Device) or a CMOS (ComplementaryMetal-Oxide-Semiconductor) sensor. As the advanced semiconductormanufacturing technologies have allowed the pixel size of sensors to bereduced and compact optical systems have gradually evolved toward thefield of higher megapixels, there is an increasing demand for compactoptical systems featuring better image quality.

A conventional optical system employed in a portable electronic productmainly adopts a three-element lens structure or a four-element lensstructure. Due to the popularity of mobile terminals with high-endspecifications, such as smart phones, tablet personal computers andwearable apparatus, the requirements for high resolution image qualityof present compact optical systems increase significantly. However, theconventional optical systems cannot satisfy these requirements of thecompact optical systems.

Other conventional compact optical systems with five-element lensstructure are disclosed. However, the refractive power and the surfaceshape of the lens elements are not favorable for forming a telephotostructure and providing the first lens element (which is the lenselement closest to an object side of the optical system) with sufficientlight converging ability. Furthermore, the focal lengths of the lenselements and axial distances between the lens elements are not favorablefor providing sufficient space for controlling optical paths of thelight rays entering into the optical system while controlling therefractive power of the first lens element. As a result, a long-shotscene cannot be clearly imaged on an image surface of the opticalsystem, and the image quality is poor.

DETAILED DESCRIPTION

A photographing optical lens assembly includes, in order from an objectside to an image side, a first lens element, a second lens element, athird lens element, a fourth lens element and a fifth lens element. Thephotographing optical lens assembly has a total of five lens elementswith refractive power. No relative movement is between any two of thefirst lens element, the second lens element, the third lens element, thefourth lens element and the fifth lens element. That is, thephotographing optical lens assembly is a fixed-focus optical system, andan axial distance between any two of the first lens element, the secondlens element, the third lens element, the fourth lens element and thefifth lens element adjacent to each other is fixed.

An axial distance is between any two of the first lens element, thesecond lens element, the third lens element, the fourth lens element andthe fifth lens element adjacent to each other. That is, each of thefirst lens element, the second lens element, the third lens element, thefourth lens element and the fifth lens element is a single andnon-cemented lens element. Moreover, the manufacturing process of thecemented lens elements is more complex than the non-cemented lenselements. In particular, a second surface of one lens element and afirst surface of the following lens element need to have accuratecurvature to ensure these two lens elements will be highly cemented.However, during the cementing process, those two lens elements might notbe highly cemented due to displacement and it is thereby not favorablefor the image quality of the photographing optical lens assembly.Therefore, the photographing optical lens assembly of the presentdisclosure provides five single and non-cemented lens elements foravoiding the problem generated by the cemented lens elements.

The first lens element with positive refractive power has a convexobject-side surface, and can have a convex image-side surface.Therefore, the light converging ability of the first lens element can beenhanced, and the total track length of the photographing optical lensassembly can be reduced.

The second lens element can have negative refractive power, and can havea convex object-side surface and a concave image-side surface.Therefore, the aberration of the photographing optical lens assembly canbe effectively corrected so as to improve the image quality.

The third lens element can have negative refractive power, and can havea concave object-side surface and a convex image-side surface.Therefore, the astigmatism of the photographing optical lens assemblycan be effectively corrected so as to improve the image quality.Furthermore, at least one of the object-side surface and the image-sidesurface of the third lens element can have at least one inflectionpoint. Therefore, the aberration of the off-axis field can be corrected.

The fourth lens element can have positive refractive power, and can havea convex image-side surface. Therefore, the distribution of the positiverefractive power of the photographing optical lens assembly can bebalanced so as to reduce the photosensitivity thereof.

The fifth lens element can have negative refractive power, and can havea convex object-side surface and a concave image-side surface.Therefore, the astigmatism of the photographing optical lens assemblycan be effectively corrected so as to improve the image quality.Furthermore, at least one of the object-side surface and the image-sidesurface of the fifth lens element has at least one inflection point.Therefore, the aberration of the off-axis field can be corrected, sothat the high image quality can be obtained.

When a focal length of the first lens element is f1, and an axialdistance between the third lens element and the fourth lens element isT34, the following relationship is satisfied: 0<f1/T34<4.0. Therefore,the axial distance between the third lens element and the fourth lenselement can be adjusted for providing sufficient space for controllingoptical paths of the light rays entering into the photographing opticallens assembly while controlling the refractive power of the first lenselement. Thus the image quality of the long-shot can be improved.Preferably, the following relationship can be satisfied: 0<f1/T34<3.30.More preferably, the following relationship can be satisfied:0<f1/T34<2.85.

When a focal length of the photographing optical lens assembly is f, anda maximum image height of the photographing optical lens assembly isImgH, the following relationship can be satisfied: 2.00<f/ImgH.Therefore, the photographing range can be favorably controlled forclearly imaging a distance scene on an image surface of thephotographing optical lens assembly.

The photographing optical lens assembly can further includes a stop,such as an aperture stop. When an axial distance between the stop andthe image-side surface of the fifth lens element is SD, and an axialdistance between the object-side surface of the first lens element andthe image-side surface of the fifth lens element is TD, the followingrelationship is satisfied: 0.75<SD/TD<1.2. Therefore, the telecentricityand the wide-angle character of the photographing optical lens assemblycan be balanced. Preferably, the following relationship can besatisfied: 0.85<SD/TD<1.0.

When a curvature radius of the object-side surface of the fifth lenselement is R9, and a curvature radius of the image-side surface of thefifth lens element is R10, the following relationship can be satisfied:|R10/R9|<3. Therefore, the surface curvatures of the fifth lens elementare proper for correcting the astigmatism and the distortion of thephotographing optical lens assembly, and the incident angle of the lightrays onto an image sensor can be effectively reduced. Accordingly, thephotosensitivity of the photographing optical lens assembly can beimproved, and the brightness or saturation at the periphery of the imagecan be maintained. Preferably, the following relationship can besatisfied: |R10/R9|<0.9.

When an axial distance between the first lens element and the secondlens element is T12, an axial distance between the second lens elementand the third lens element is T23, the axial distance between the thirdlens element and the fourth lens element is T34, and an axial distancebetween the fourth lens element and the fifth lens element is T45, T34is greater than T12, T23 and T45. Therefore, the axial distance betweenthe third lens element and the fourth lens element can be adjusted forproviding sufficient space for controlling the optical paths of thelight rays entering into the photographing optical lens assembly.

When an Abbe number of the second lens element is V2, and an Abbe numberof the fourth lens element is V4, the following relationship can besatisfied: 20<V2+V4<65. Therefore, the chromatic aberration of thephotographing optical lens assembly can be corrected.

When the focal length of the photographing optical lens assembly is f,the focal length of the first lens element is f1, and a focal length ofthe second lens element is f2, the following relationship can besatisfied: 3.0<|f/f1|+|f/f2|. Therefore, the image quality of thelong-shot of the photographing optical lens assembly can be improved.

When a composite focal length of the first lens element and the secondlens element is f12, and a composite focal length of the third lenselement, the fourth lens element and the fifth lens element is f345, thefollowing relationship can be satisfied: −0.80<f12/f345<−0.40.Therefore, it is favorable for forming a telephoto optical system havingpositive refractive near the object side and negative refractive nearthe image side, and a long-shot scene can be clearly imaged on the imagesurface.

When the axial distance between the first lens element and the secondlens element is T12, the axial distance between the second lens elementand the third lens element is T23, the axial distance between the thirdlens element and the fourth lens element is T34, and the axial distancebetween the fourth lens element and the fifth lens element is T45, thefollowing relationship can be satisfied: 0<T12<T45<T23<T34. Therefore,the axial distances between the lens elements can be adjusted forproviding sufficient space for controlling the optical paths of thelight rays entering into the photographing optical lens assembly.Furthermore, it is favorable for assembling the lens elements.

When a half of a maximal field of view of the photographing optical lensassembly is HFOV, the following relationship can be satisfied: HFOV<25degrees. Therefore, the photographing range can be favorably controlledfor improving the image quality of the long-shot.

When the focal length of the photographing optical lens assembly is f,and an entrance pupil diameter of the photographing optical lensassembly is EPD, the following relationship can be satisfied:2.4<f/EPD<3.5. Therefore, the size of the stop can be favorablycontrolled for the light rays entering into the photographing opticallens assembly while improving the image quality of the long-shot.

When a curvature radius of the image-side surface of the second lenselement is R4, a curvature radius of the image-side surface of thefourth lens element is R8, the curvature radius of the object-sidesurface of the fifth lens element is R9, and the curvature radius of theimage-side surface of the fifth lens element is R10, the followingrelationships are satisfied: |R4|<|R8|; |R4|<|R9|; and |R4|<|R10|.Therefore, the astigmatism of the photographing optical lens assemblycan be effectively corrected so as to improve the image quality.

The refractive power of the fifth lens element can decrease from aparaxial region to an off-axis region thereof. (The result is obtainedfrom comparing the absolute values of the refractive power of the fifthlens element at different positions. When the refractive power isstronger, the absolute value of the refractive power is larger.Similarly, when the refractive power is weaker, the absolute value ofthe refractive power is smaller.) Therefore, the refractive degree ofthe incident light rays can be minimized, and the aberration can bereduced. Accordingly, the image quality at the periphery of the imagecan be improved.

When the focal length of the photographing optical lens assembly is f,the focal length of the first lens element is f1, the focal length ofthe second lens element is f2, a focal length of the third lens elementis f3, a focal length of the fourth lens element is f4, and a focallength of the fifth lens element is f5, the following relationships aresatisfied: |f/f1|>|f/f2|>|f/f5|>|f/f3|; and |f/f1|>|f/f2|>|f/f5|>|f/f4|.Therefore, the light converging ability of the first lens element can beenhanced. Accordingly, the total track length of the photographingoptical lens assembly can be reduced, and the image quality of thelong-shot can be improved.

When an axial distance between the object-side surface of the first lenselement and the image surface is TL, and the maximum image height of thephotographing optical lens assembly is ImgH, the following relationshipcan be satisfied: 2.0<TL/ImgH<3.0. Therefore, the compact size of thephotographing optical lens assembly can be maintained for applying tothin and portable electronics.

The refractive power of the first lens element is stronger than therefractive power of the second lens element, the third lens element, thefourth lens element and the fifth lens element. (The result is obtainedfrom comparing the absolute values of the refractive power of the lenselements. When the refractive power is stronger, the absolute value ofthe refractive power is larger. Similarly, when the refractive power isweaker, the absolute value of the refractive power is smaller.)Therefore, the light converging ability of the first lens element can beenhanced, and the total track length of the photographing optical lensassembly can be reduced.

According to the photographing optical lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of glass material, thedistribution of the refractive powers of the photographing optical lensassembly may be more flexible to design. When the lens elements are madeof plastic material, the manufacturing cost can be effectively reduced.Furthermore, surfaces of each lens element can be arranged to beaspheric, since the aspheric surface of the lens element is easy to forma shape other than spherical surface so as to have more controllablevariables for eliminating the aberration thereof, and to furtherdecrease the required number of the lens elements. Therefore, the totaltrack length of the photographing optical lens assembly can also bereduced.

According to the photographing optical lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to the opticalaxis, and the off-axis region refers to the region of the surface awayfrom the paraxial region. Particularly, if not stated otherwise, whenthe lens element has a convex surface, it indicates that the surface isconvex in the paraxial region thereof; when the lens element has aconcave surface, it indicates that the surface is concave in theparaxial region thereof. Furthermore, if not stated otherwise, therefractive power or the focal length of the lens element, that is,refers to the refractive power or the focal length in a paraxial regionof the lens element.

According to the photographing optical lens assembly of the presentdisclosure, an image surface of the photographing optical lens assembly,based on the corresponding image sensor, can be flat or curved. Forinstance, the image surface can be a curved surface being concave facingtowards the object side.

According to the photographing optical lens assembly of the presentdisclosure, the photographing optical lens assembly can include at leastone stop, such as an aperture stop, a glare stop or a field stop. Saidglare stop or said field stop is for eliminating the stray light andthereby improving the image resolution thereof.

According to the photographing optical lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. A front stop disposed between an imaged object and thefirst lens element can provide a longer distance between an exit pupilof the photographing optical lens assembly and the image surface andthereby improves the image-sensing efficiency of an image sensor. Amiddle stop disposed between the first lens element and the imagesurface is favorable for enlarging the field of view of thephotographing optical lens assembly and thereby provides a wider fieldof view for the same.

The photographing optical lens assembly of the present disclosure alsocan be applied to 3D (three-dimensional) image capturing applications,in products such as digital cameras, mobile devices, digital tablets,smart TV, internet monitoring device, game consoles with motion sensingfunction, driving recording systems, rear view camera systems, andwearable devices.

According to the present disclosure, an image capturing device isprovided. The image capturing device includes the aforementionedphotographing optical lens assembly and an image sensor. The imagesensor is disposed on the image side of the photographing optical lensassembly, that is, the image sensor can be disposed on or near the imagesurface of the aforementioned photographing optical lens assembly. Thefirst lens element of the photographing optical lens assembly haspositive refractive power, which is favorable for forming a telephotooptical system having positive refractive power near the object side andnegative refractive power near the image side. The first lens elementhas the convex object-side surface, so that the light converging abilityof the first lens element can be enhanced. Moreover, the axial distancebetween the third lens element and the fourth lens element can beadjusted for providing sufficient space for controlling optical paths ofthe light rays entering into the photographing optical lens assemblywhile controlling the refractive power of the first lens element. As aresult, the image quality of the long-shot can be improved. Furthermore,the focal length of the photographing optical lens assembly and themaximum image height of the photographing optical lens assembly can beadjusted, so that the photographing range can be controlled for clearlyimaging a distance scene on the image surface of the photographingoptical lens assembly. Preferably, the image capturing device canfurther include a barrel member, a holding member or a combinationthereof.

According to the present disclosure, an electronic device is provided.The electronic device includes the aforementioned image capturingdevice. Therefore, the image quality of the long-shot can be improvedand a distance scene can be clearly imaged on the image surface whilethe compact size of the electronic device is maintained. Preferably, theelectronic device can further include but not limited to a control unit,a display, a storage unit, a random access memory unit (RAM), a readonly memory unit (ROM) or a combination thereof.
